Jade goes to the mall to buy a pair of shoes for $60 dollars, two shirts for $25 each and three pants for $50 each. She has a coupon for 30% off.
How much was the discount?
A.$95.00
B.$78.00
C.$260.00
D.$138.00

B. $78.00

Step-by-step explanation:

60 + 25(2) + 50(3) - We can simplify this.

60 + 50 + 150 = 260

30% of 260 is 78.

0.3 x 260 = 78.

So, the discount was $78.00.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
